And when something goes wrong, the PM is often the target of any resulting litigation along with the landlord.

Hey @Ryan Marble, it is something that you can do no problem, like the others have said.Regarding figuring out your return, take some time and look at all the listings that would be similar to what you are planning on AirBNB and VRBO.Look at their nightly rates, occupancy and amenities.

Usually they call the handyman first if they have a problem like no heat or a water leak or something.

I dealt with something similar before.

Although it varies between hard money lenders, expect to pay something along the lines of between 10-25% of purchase price, and they will usually fund something like 100% of renovations up to 75% ARV (rest would come out of pocket).

Something that is solid and you can see improving over time. 

This is something I can work on and I think most everyone can.

If you want to "rig" something up from outside your windows and all then... again you'll have to verify what your housing owners allow or not (just like a satelite dish).

Usually it's the customer changing their mind about something. 

As for noise from up-stairs, I would probably try installing new ceilings over the existing ones using something like resilient channel but this really isn't easy while occupied. https://www.clarkdietrich.com/products/resilient-channel-sys...
